Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An emergency light system comprising: a combined sensor/emergency light unit ( 18 ), the combined sensor/emergency light unit comprising: at least one emergency light means ( 16 ), one emergency light ( 15 ) unit, and one rechargeable storage device ( 17 ) for electrical energy, wherein the emergency light unit ( 15 ) is adapted to supply electrical energy to a low-voltage power supply connection, from DC bus voltage, for charging the storage device ( 17 ) with electrical energy; a bus ( 2 ), which supplies DC voltage in standby state; and a bus signal generator, which is connected to the bus ( 2 ) and which further loops the bus voltage to the integrated or separately provided emergency light unit ( 15 ).
An emergency lighting system has a combined sensor and emergency light unit. This unit includes emergency lights, an emergency light control unit, and a rechargeable battery. The emergency light control unit charges the battery from a low-voltage DC bus. The system also includes a DC bus that provides voltage when the system is in standby. A bus signal generator connects to the bus and loops the bus voltage to the emergency light control unit, which can be integrated or separate.
2. The emergency light system according to claim 1 , wherein the emergency light unit ( 15 ) is adapted to monitor the voltage at the low-voltage supply connection and to evaluate a long-term voltage failure as an emergency light situation and accordingly to activate the emergency lighting means ( 16 ).
The emergency light system described above includes an emergency light control unit that monitors the voltage at its low-voltage power supply connection. If the voltage fails for a significant period, the unit interprets this as an emergency situation and activates the emergency lights. In other words, the system automatically switches to emergency lighting mode upon detecting a prolonged power outage.
3. An emergency light unit ( 15 ) for a lighting system, which is connected to a bus ( 2 ) of the lighting system, and to a rechargeable storage device ( 17 ) for electrical energy and to an emergency lighting means ( 16 ), wherein current from the bus ( 2 ) can be supplied for recharging to the storage device ( 17 ) and wherein the emergency light unit ( 15 ) is integrated or connected with a bus-capable sensor module control device ( 20 ).
An emergency light unit for a lighting system connects to the lighting system's bus, a rechargeable battery, and emergency lights. The unit recharges the battery using current from the bus. Critically, the emergency light unit is integrated with, or connected to, a sensor module control device that can communicate on the bus. This allows for combined sensor and emergency light functionality in a single unit that communicates with a larger lighting control system.
4. The emergency light unit ( 15 ) according to claim 3 , wherein the emergency light unit is arranged together with: the control device ( 20 ), the storage device ( 17 ) for electrical energy, and the emergency light means ( 16 ) in a joint housing ( 21 ).
The emergency light unit described above, which connects to a lighting system bus, a rechargeable battery, and emergency lights while integrating with a bus-capable sensor module, has all of its components - the control device, battery, and emergency lights - housed together in a single, joint enclosure. This provides a compact and integrated emergency lighting solution.
5. The emergency light unit ( 15 ) according to claim 3 , further comprising sensor optics ( 19 ) and wherein a cavity is provided in the housing ( 21 ) which is opened at a top portion thereof for attachment to a ceiling for illumination of a specific area, so that the sensor optics ( 19 ) and an emergency lamp ( 16 ) protrude from a bottom side thereof.
The emergency light unit as described above (connected to a bus, battery, and emergency lights; integrated with a bus-capable sensor module) includes sensor optics. The unit also has a housing with a cavity that's open at the top for mounting to a ceiling for illuminating a specific area. The sensor optics and emergency lamp protrude from the bottom of the housing. The design optimizes coverage for both sensing and emergency lighting downwards from the ceiling mount.
6. The emergency light unit ( 15 ) according to claim 5 , wherein the housing ( 21 ) is a rotationally symmetrical body, and the sensor optics ( 19 ) are arranged in a central position and surround by a plurality of LEDs ( 16 ) in an annular shape forming the emergency light.
The emergency light unit, which is connected to a bus, battery, and emergency lights, integrates with a bus-capable sensor module, includes sensor optics, and mounts in a ceiling cavity, has a rotationally symmetrical housing. The sensor optics are located centrally, surrounded by a ring of LEDs that function as the emergency light. The circular design ensures even light distribution and consistent sensor coverage.
7. The emergency light unit ( 15 ) according to claim 3 , wherein the storage device ( 17 ) for electrical energy is a rechargeable battery.
The emergency light unit, which is connected to a bus, battery, and emergency lights while integrating with a bus-capable sensor module, utilizes a rechargeable battery as the storage device for electrical energy. The battery provides the power for the emergency lights when the main power source is unavailable.
